I purchased this a a replacement for a product that was no longer available from another company. It's used in multiple scenarios and I find it to be very smooth and adaptable to different situations and products. The product does not have a description that gives it a speed rating aka: Fast /Slow/Extra Slow.
From what I've experienced so far, it's somewhere between slow and fast. Good all around quality product, will definitely order again when needed! OH! - and great fast service!!! THX!!!
